Just be careful, though (writing as a native English speaker), because 
the word 'polymath' for English speaker is not a reference to 
mathematicians at all. (Greek/mathē/ means 'learning' not mathematics). 
Translators are well aware of the danger of homonyms, and if you go for 
a title like Manual for Polymathematicians, then the word is being 
wrongly used. There is a word 'polymath' in English, but not 
'polymathematician', unless of course you make it clear that it is 
merely a play on words. But personally, I'd avoid that.
